Why is DUAL called "DUAL"?

61224Jun 5 2003 — edited Jun 6 2003
Apologies if this has been asked before, but I can't seem to find it in the search:

Why is the DUAL table called "DUAL"? Is it meant to stand for something, a special meaning, or just a random name picked out of the hat (and one which people are not likely to use as their own table name)?

Cheers.
